HOISTING DEVICE.

Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed January 17,1906. Serial No. 296,469.

To (ti/Z whom it may concern:

Be it known that 1, CHARLES T. WALES, a citizen of the United States, residing at New Brunswick, in the county of MiddleseX and State of New Jersey, have invented certain new and useful Improvements in Hoisting Devices, of which the following is a specification.

My invention relates to improvements in hoisting devices, and particularly to hoisting devices used for raising and lowering pianos, safes, and the like through the windows of buildings.

The object of my invention is to construct a hoist in such a manner that the same may be attached to a building adjacent a windowopening, and when so attached the load or strain will be taken by the walls of the building and not by the window-frame.

A further object of my invention is to construct the hoist in two parts, one consisting of a rectangular frame which is placed inside of the building and forms a means for supporting the other part of the hoist which is laced on the outside of the building.

A still further object of my invention is to provide a means for supporting a temporary platform beyond the line of the building.

In the drawings, Figure 1 is a side view of the hoist attached to a window, showing the window in section. Fig. 2 is a front view of the hoist, showing the window in dotted lines; and Fig. 3 is a rear view of the rectangular frame which is placed on the inside of the window.

Referring to the drawings, A is a rectangular frame consisting of upper and lower crosspieces a and a and side pieces a and a which latter are made adjustable so that the length of the frame may be varied. The cross-pieces a, and a may also be bolted to the side pieces at various places for purposes of adjustment. The cross-piece a carries supporting-plates B and B, having hooks b formed on their outer ends and reinforcingpieces I), which rest upon the window-sill and take the mainportion of the load.

The portion of the hoisting device which goes on the outside of the building and which is supported by the hooks 1) consists of a rectangular frame C and the block-carrying arms D, having their side members secured to the frame 0 at the points (1 and d and their upper portions secured by the braces C and the stay-rods E and the whole securely held in position by the tie-rods F, which are attached to the cross-piece a of the frame A. The arms D are connected at their upper ends by a cross-piece D, on which is suspended the block D The tie-rods F are provided with turnbuckles a, so that the inner and outer frames may be drawn securely together.

Pads G and G, preferably made of leather, are secured to the ends of the cross-piece a to prevent the said cross-piece from defacing the wall of the building.

The arms D are provided with a swinging beam H, supported by rods h, pivoted to the arms D at the points it. This beam H forms a support for planks, as shown in dotted lines, Fig. 1, which may be placed on the beam H after the object has been raised sufficiently to clear the planks. A platform is thus formed on which the object may be lowered and conveyed into the building or for a like purpose when the object is being taken from the building.

The operation of my invention is as follows The frame A is placed on the inside of the building with the side pieces a and a resting on the floor and the pads G and G adjusted to bear against the walls at either side of the Window-opening and as close to the ,top of the same as possible. The supporting-plates B and B are adjusted so as to rest upon the window-sill with the hooks Z) projecting out ready to receive the outside portion of the hoist, which is then raised so that the lower cross-bar of the frame 0 will be engaged by said hooks, when the upper part of the frame C may be drawn into position by the tie-rods F and F. It will be seen that by constructing a hoist in this manner it may readily be attached to any building and that the strain will be taken by the walls and not by the win dow-frame, which in many instances would not be strong enough to support the object to be hoisted.

The hoist is also made of light material, so that it can readily be handled, and at the same time it is so braced that it will be able to carry a heavy load, and said braces permit the arms D to be made long to give sufficient head room for the block and tackle. The swinging beam for supporting the platform is also of great advantage in handling heavy objects.

Having thus described my invention, I claim and desire to secure by Letters Pat ent- 1. In a hoist of the character described,

ICC

the combination, of an inner rectangular frame, an outer rectangular frame, supporting-plates carrying said outer rectangular frame, tie-rods connecting said inner and outer frames and means for attaching a block to said outer frame, substantially as described.

2. In a hoist of the character described, the combination of an outside frame, arms secured thereto, a block on said arms, an inner rectangular frame having adjustable side pieces, supporting-plates and tie-rods between said inner and outer frames, substantially as described.

3. In a hoist of the character described, the combination of an outside frame, arms attached to said frame, a block on said arms,

stay-rods and braces between said frame and said arms, an inner rectangular frame and means for supporting said outside frame by said inner frame, substantially as described. 4. In a hoist of the character described, the combination of an outside frame, arms secured thereto, a block on said arms, a swinging beam to support a platform, an inner rectangular frame, and means for supporting said inner and outer frames, substantially as described.

In testimony whereof I afliX my signature in presence of tWo Witnesses.
